rimusr BEARINGQ- This invention relates to, thrust bearings and it has for its object to provide an improved device of ,thislnature' constructed in suchmanner as to secure moreeflicient lubrication of the abuttingfaces than has,

. heretofore been possible and to providefxfor more ready dissipationof theheatinduced Further objects and advantages of the in- .vention, J will 'be. -set, forthr in the detailed description which follows. In'the accompanying drawing F lg. 1 isga side; elevation of constructed vention.

. Fig. .3 is a face view 'of the stationary member of .the bearing.

Fig.- 4 is a sectional view upon line 4'4 a bearing Fig; 5 is a face view of the contactplate or washer of the movable member of the .bearing.

Fig. 7 is a rear view of the structureof,

Fig. 9 is a modified. form of wear plate adapted to be used in .lieu of the structure of Fig. .5.

Fig. 10 is an edge elevation of the structure of Fig. 9 and Fig; 11 is an enlarged sectional view onthe line 11 11 of Fig. 9.

Like numerals designate corresponding parts in allofthe figures of the drawing. The thrust bearing of the present inven tion-is particularly'adapted foruse in con-' 1 nection 'with centrifugalpumps, though as this description proceeds it will be seen that the invention is by no means limited to that particular use;

It is -comm on practice in centrifugal pumps" to provide thrust bearings which run in an oil bath up tothelevel of'the shaft. .However,' the bearings at present in use do not provide for an adequate feed of the oil-to the contacting faces of the bearing,

. which is one'of the primary objects of the present invention.

The spacing of the' wear plate 81 from the adjacent face of the flange 12, provides a space 23' which serves thejdouble function of receiving the oil for passage to the face of the wear plate and of providing a heat breaker space," which aids in dissipating the heat induced by friction and to bring about a much more eflicient cooling of the, bears .7 that is, it is provided with a plurality of radial recesses 25, which are connected by oil ducts 26 with the working face of the plate. Ribs 27 and bosses or projections 28, serve the same purpose as the corresponding ribs and bosses of the structure of Fig.6.

- It is to be understood that the invention is not K limited to any particular physical structure, because many modifications of the structure may be resorted to, and many ways maybe devised ofholding the wear plate upon the nut 9rin such'manner' as to cause the two tomo've together. As faras we are aware we are the first to provide a wear plate of this character having means of conducting oil therethrough to the working I face thereof while mounting the same in such spaced relation to the abutment as to provide a-heat breaker'space, in the manner herein shown and described. Therefore, we

a fixed bearing member in which said shaft rotates, there being peripheral recesses formed in said bearing member, and oil ducts leading from said recesses to the Working face of said member, an abutment carried by the shaft, a rotative wear plate secured to the abutment and held in spaced relation thereto, to provide a space between the wear plate and the abutment, there.

being oil ducts leading from said space' through the plate'to the working face of the plate.

In testimony whereof they alfix' their signatures. G l V V JULIUS SEYMOUR.
